Garage Door Services in Somerset, TX
Garage door problems in Somerset usually trace back to two culprits: the expansive black clay soil beneath your slab and the brutal South Texas heat beating down on your hardware. We dispatch crews to Somerset from our San Antonio office, and most calls are completed in a single visit because our trucks carry the springs, cables, openers, and hardware needed for rural-to-suburban homes like yours. Call (210) 972-1317 and a live person will answer, any hour of any day.
We’ve been at this since 1984. That’s 42 years of showing up when we say we will, stating the price before the first bolt turns, and standing behind the work for 90 days in writing. Somerset homeowners don’t need a sales pitch. They need someone who understands why their door keeps going out of square every autumn.

Why Somerset’s Climate & Housing Affect Garage Door
Somerset sits on some of the most aggressive expansive clay soil in Texas. The black Vertisol beneath your garage slab swells when the fall rains arrive and shrinks during the long dry summers. That seasonal heave doesn’t just crack driveways. It racks garage door frames, bows headers, and throws tracks far enough out of alignment that the door won’t seal or, in worse cases, won’t close at all.
We get calls every October after the first heavy thunderstorms. The homeowner describes a “broken” door that was fine in August. Our technician arrives, levels the frame, and explains that the door itself is sound - the ground beneath it moved. This is routine work in Somerset and almost unheard of on San Antonio’s limestone-dominant north side. Adjustment and weatherseal replacement become a near-annual maintenance item here, not a luxury.
The housing stock complicates things further. Older manufactured homes, common in southern Bexar County, often have single-bay steel doors or carports that were enclosed after the fact. Those conversions frequently use non-standard rough openings, which means off-the-shelf doors won’t fit without modification. We’ve learned to measure twice and cut once, because ordering a door that doesn’t fit costs everyone time and money.
Then there’s the heat. Somerset garages often lack the attic buffers and ventilation of newer San Antonio construction. Sustained 100°F temperatures degrade torsion spring lubricant into a gummy residue that accelerates metal fatigue. Vinyl door sections warp. Opener motors overheat and fail prematurely. The February 2021 ice storm taught us another lesson: cold-weather spring failures happen here too, despite the subtropical reputation, because doors that never see freezing conditions aren’t maintained for them.

FAQs About Garage Door in Somerset
Spring replacement in Somerset typically runs $180 to $340, depending on whether you need torsion or extension springs and whether the door requires additional adjustment for frame alignment. We quote the exact price before starting, and our $50 off repair-over-$250 offer applies. Call (210) 972-1317 for a free estimate.
Somerset’s expansive black clay soil swells with fall rain and shrinks during summer drought, racking garage door frames in a cycle that repeats annually. This is foundation movement, not a faulty door, and it requires seasonal adjustment rather than replacement. We’ve explained this to hundreds of homeowners in the 78069 ZIP code - it’s simply the reality of building on Vertisol soil.
Yes. Manufactured home garage conversions are common in Somerset, and we regularly install custom-fit doors for non-standard rough openings. We measure on-site, order or modify the correct door, and install it without the gaps and compromises you’ll get from a one-size-fits-all approach. Learn more about our installation service.
We stock parts and are factory-familiar with all major brands, including Craftsman and Raynor. Our trucks carry drive gears, circuit boards, safety sensors, and remotes for most models produced in the last two decades.

What Somerset Customers Say
"Logic board on a fifteen year old opener. He was straight with me that a new opener would cost less than the board plus the labor, and he was right. No pressure either way."
- Emily Novak"Both cables had come off the drum and the door was hanging at an angle. I had watched a video and was about ten minutes from trying it myself, which he told me would have been a genuinely bad idea."
- Marisol Delgado"Good repair at a fair price. The door still has a slight shudder about a foot from the top, which he said is the frame being out of true on an old build and would cost real money to fix properly. Fair enough, but I had hoped for perfect."
- Laura Mercer
